Description
I'm working with the example here: http://codepen.io/plotly/pen/PzmNXP
Running Plotly.toImage(graph, {format: 'png', width: 200, height: 150})
gives
[[PromiseValue]]: TypeError: Cannot set property 'cmin' of undefined at e.exports (https://cdn.plot.ly/plotly-latest.min.js:29:1601) at e.exports (https://cdn.plot.ly/plotly-latest.min.js:43:14111) at Object.e.exports [as calc] (https://cdn.plot.ly/plotly-latest.min.js:43:28774) at h (https://cdn.plot.ly/plotly-latest.min.js:33:3912) at Object.P.plot (https://cdn.plot.ly/plotly-latest.min.js:33:18628) at https://cdn.plot.ly/plotly-latest.min.js:34:7453 at Object.n [as toImage] (https://cdn.plot.ly/plotly-latest.min.js:34:6706) at <anonymous>:1:8
Similarly, clicking the "Download plot as png" icon in the hoverbar gives a status that says:
"Sorry, there was a problem downloading your snapshot!"
